The PETdisk is a new storage device, made by bitfixer, for the Commodore CBM / PET with an IEEE-488 port.

The system is in two parts. A datassette module that makes it possible to play “data” from a PC soundcard to the CBM / PET and play “data” from the CBM / PET to the PC. The IEEE-488 module has an SD card and a micro processor.

You can use the commands LOAD, SAVE and LOAD “$” to load or store data on the SD card. The device number can be changed with a help of a jumper. The USB cable is used to provide 5VDC from the datassette module to the IEEE-488 module.

If your CBM/PET is like mine, the keyboard is probably not working too well, nor is it easy to use. Here is the answer: A PS/2 interface that lets you connect a regular Personal Computer keyboard (with PS/2 connector) to your PET/CBM.

The interface is installed inside the PET/CBM and does not take up any ports, other than an internal expansion power connector. As an added bonus, pressing Ctrl + Alt + Del on the keyboard will reset your pet.

This is a small adapter which replaces the unobtanable 6540 ROM chips used in the Commodore PET 2001-8 computers with a standard 2716 EPROM.

They will work as a drop in replacement for any ROM chip in a PET 2001-8.
